BACKGROUND

It has become common for merchants to utilize an electronic forum that provides users with the ability to view and/or purchase items using an electronic catalog of items. As an example, users may view information related to an item in an electronic catalog by simply submitting a search query for the item via a search engine. The search query may typically include a set of words or phrases that a user enters when looking for information about a specific item. Oftentimes it is not easy for a user to choose query terms that specifically represent information about an item. As a result, users tend to modify their initial queries and submit new ones that more accurately reflect their information needs. In addition, users may also narrow or broaden their queries during a search session in the hope of getting better search results.

DETAILED DESCRIPTION

In the following description, various embodiments will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the embodiments may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.

Some or all of the processes described herein, or variations and/or combinations thereof may be performed under the control of one or more computer systems configured with executable instructions and may be implemented as code (e.g., executable instructions, one or more computer programs or one or more applications) executing collectively on one or more processors, by hardware or combinations thereof. The code may be stored on a computer-readable storage medium, for example, in the form of a computer program comprising a plurality of instructions executable by one or more processors. The computer-readable storage medium may be non-transitory.

Techniques described herein include a method and system for analyzing user behavior as a user searches for items, for example within an electronic marketplace. In accordance with at least one embodiment, a query is submitted by a user of the electronic marketplace, the query is processed to identify one or more actions or behaviors performed by the user in relation to the query and fingerprint information for the query is determined based at least in part on the query and the one or more actions or behaviors. In some embodiments, a user experience for the user is modified based at least in part on the fingerprint information.

In some examples, the actions performed by a user in relation to a query may include, without limitation, a re-formulation of the query, a term swap, a term addition, a term deletion, an abandonment of the query, an item detail page click, a refinement of the query, a scope change of the query, and the like. For example, a re-formulation, a refinement or a scope change of a query may include a modification to search terms of the query by the user. Similarly, a term addition may include the addition of one or more search terms to a query. A term deletion may include the removal of one or more search terms to a query. An item detail page click may include the selection of an item in the electronic catalog by the user, to view details about the item. As an example, an item detail page may include details that characterize an item offered for sale in the electronic marketplace and may include information that assists users (e.g., buyers) to decide between multiple alternative offers related to the item. Query abandonment may include an abandonment of the query by the user.

In accordance with at least one embodiment, a plurality of fingerprints are analyzed to form a classification system or database of fingerprints. In one embodiment, a fingerprint for a query may be represented as a vector of features comprising fingerprint information. The fingerprint information may, in some examples, identify one or more actions performed by users in relation to a query during a search session. In other examples, the fingerprint information may also identify time information. The time information may, in some examples, represent an average amount of time spent by one or more users while browsing for information during a search session. Using this classification system or database, a new query can be classified within the classification system and handled accordingly, for example by anticipating actions of a user that submitted the query and modifying the user's experience accordingly.

In certain embodiments, a user may, via a computing device, submit a search query for an item to a search engine provided by an electronic marketplace website. The electronic marketplace may receive the query submitted by the user and access a classification database having fingerprint information. In one example, the electronic marketplace may then determine fingerprint information for the query by comparing the fingerprint information in the classification database to an action performed by the user in relation to the query. In one embodiment, the electronic marketplace may then determine a classification for the query based on the fingerprint information. In some embodiments, the electronic marketplace may modify a user experience for the user based at least in part on the fingerprint information.

Modifying a user's experience, in some examples, may include modifying search results presented to the user by arranging items of the search results in accordance with one or more layouts and/or views based on query fingerprint information. Modifying search results may include generating an interactive network region comprising the search results related to a query issued by a user, based on fingerprint information. In some examples, modifying search results may include identifying various categories of items related to a query issued by the user based on fingerprint information, organizing the search results based on categories, ordering the categories based on fingerprint information and identifying a subset of items related to a subset of categories (e.g., the most popular categories) in the search results.

In at least one limiting example, a user on a computing device interacts with an electronic marketplace website via a browser application on the computing device by submitting a query (e.g., ‘Shoes’) via a search interface provided by the electronic marketplace website. The electronic marketplace may identify a subsequent action that the user is likely to perform in relation to the query ‘shoes’ based on fingerprint information stored in the classification database. As an example, the electronic marketplace may identify that a subsequent action may be a ‘term addition’ to the query that describes, for example, additional characteristics of the query ‘Shoes’ such as a color, size, particular brand of the shoes and the like. In one embodiment, the electronic marketplace may dynamically modify search results presented to the user to include items related to these additional characteristics. In one example, the search results presented to the user may be modified by arranging the items of the search result as a ‘list’ of scrollable items, based on the fingerprint information. In other examples, the search results presented to the user may be modified by arranging the items of the search result in a two-dimensional, scrollable ‘grid’ layout, based on the fingerprint information or by displaying ‘images’ of the items of the search result, based on the fingerprint information.

In at least one limiting example, a user on a computing device interacts with an electronic marketplace website via a browser application on the computing device by submitting a query (e.g., ‘Games) via a search interface provided by the electronic marketplace website. The electronic marketplace determines a fingerprint for the query based on fingerprint information stored in the classification database. For example, the fingerprint for the query may indicate a set of actions performed by a plurality of users of the electronic marketplace in relation to the query ‘Games’ such as, for example, a re-formulation of the query to ‘Video Games,’ a term addition to the query, such as ‘Apps for Video Games,’ a term deletion in the query to just, ‘Toys and Games,’ and so on. In one embodiment, the electronic marketplace may identify various categories related to the query based on the identified search terms, ‘Video Games,’ ‘Apps for Video Games,’ Toys and Games' in the query fingerprint and generate an interactive network region comprising a ‘filmstrip’ of categories related to the query based on these search terms. In embodiments, the electronic marketplace may modify the search results presented to the user by providing information for rendering a network page comprising the various identified categories arranged in a ‘filmstrip’ to the user based on the query fingerprint.

In at least one limiting example, a user on a computing device interacts with an electronic marketplace website via a browser application on the computing device by submitting a query (e.g., ‘Best home theater system’) via a search interface provided by the electronic marketplace website. In accordance with one embodiment, the electronic marketplace may identify the term ‘Best’ in the query as a comparison term and identify a list of comparable items related to the query based on fingerprint information related to the query. For example, the electronic marketplace may determine that fingerprint information related to the query ‘Best home theater system’ includes one or more re-formulations of the query to ‘Top reviewed home theater systems,’ ‘Most reviewed for home theatre systems,’ and the like. In one embodiment, the electronic marketplace may identify terms such as ‘Top,’ ‘Most reviewed,’ and the like as comparison terms and generate an interactive network region comprising a ‘filmstrip’ of information that identifies a list of comparable items such as ‘#1 Best Seller,’ ‘Top Reviewed,’, ‘Most Wished For,’ and ‘Special Offer,’ home theater systems, based on the fingerprint information.

In at least one limiting example, a user on a computing device interacts with an electronic marketplace website via a browser application on the computing device by submitting a query (e.g., ‘Star Wars’) via a search interface provided by the electronic marketplace website. In one embodiment, the electronic marketplace may dynamically modify search results presented to the user by identifying theme information in the query and identifying items that correspond to various characteristics of the theme based on the query fingerprint. As an example, the items may include various characteristics of the theme of the query such as ‘Movies #,’ ‘T-shirts #,’ ‘Collectibles #,’, ‘Sales& Deals #,’ ‘Costumes #,’ ‘Games #,’ ‘Legos #,’ and the like. In some embodiments, the electronic marketplace may be configured to arrange the items in at least one of a grid layout, a list layout or an image layout in a network page rendered to the user based on the theme.

FIG. 1 depicts aspects of an example system architecture 100 in accordance with at least one embodiment of the present disclosure. The architecture 100 includes an electronic marketplace 112 communicatively connected to one or more user computing devices 102, 104, 106 and 108 via a network 110. The electronic marketplace 112 may present items for sale from one or more sellers and facilitate transactions (e.g., financial transactions) with respect to the items. A user of the electronic marketplace 112 may view and/or order items from the electronic marketplace 112 using one or more of the computing devices 102, 104, 106 and 108. In one embodiment, the electronic marketplace 112 may be hosted by one or more service provider computers, described herein. An exemplary implementation of the electronic marketplace in accordance with at least one embodiment is described below in more detail with reference to FIG. 2.

In architecture 100, one or more users (i.e., electronic marketplace consumers or web browser users) may utilize a browser application or other web application on the user computing devices 102, 104, 106 and 108 to interact with an electronic marketplace website which may be hosted, managed, and/or provided by the electronic marketplace 112, described herein. As an example, users may interact with the electronic marketplace website to search for, browse for, or purchase items from the electronic marketplace 112. As described herein, an item may include a physical item of manufacture, a media item, a digital item (for e.g., music, movie or software), and/or a service (e.g., a virtual computer that provides specific services to users) or other items for purchase or selection via a networked environment.

In accordance with at least one embodiment, the electronic marketplace 112 may be configured to perform one or more operations to receive one or more queries Q1, Q2, Q3 . . . Qn issued by one or more users on user computing devices 102, 104, 106 and 108 and store the queries in a user behavior database 114. In one embodiment, the user behavior database 114 may maintain time-stamped search query histories of search queries submitted by users of the electronic marketplace during a search session. In other examples, the user behavior database 114 may also maintain item browse histories and item purchase histories of users of the electronic marketplace. The item browse histories may identify items selected by users for viewing and indicate the date and time for each such item browse event. The item purchase histories may identify all the items purchased by users of the electronic marketplace and the associated dates of purchase.

In one embodiment, the electronic marketplace 112 may access the search query histories stored in the user behavior database 114 to identify a query submitted by users of the electronic marketplace. The electronic marketplace 114 may then perform one or more operations to identify a series of actions performed by the users in relation to the query during a search session. The actions may include, for example, a re-formulation of the query, a term swap, a term addition, a term deletion, an abandonment of the query, an item detail page click, a refinement of the query, a scope change of the query, and the like. The electronic marketplace 114 may then generate fingerprint information for the query 118 based at least in part on analyzing the actions.

In certain embodiments, the fingerprint information for each query may be stored in a query classification database 116. In accordance with at least one embodiment, the electronic marketplace 112 may be configured to determine a classification for the query 120 based at least in part on the fingerprint information and store the classification information in the query classification database 116. In one example, a query submitted by the user may be classified as a ‘Broad’ query, a ‘Well-defined query’, a ‘Brand query’, and the like based on the fingerprint information. Additional details regarding the generation and classification of fingerprint information related to queries submitted by users of an electronic marketplace is discussed in detail in relation to FIG. 3.

In accordance with at least one embodiment, the electronic marketplace 112 may be configured to perform one or more operations to evaluate a fingerprint for a query and modify a user experience for the user 122 based on the fingerprint. As an example, the electronic marketplace 112 may receive a first query submitted by a user of a user device (e.g., 102). The electronic marketplace may then access a classification database having fingerprint information. In one example, the electronic marketplace may determine fingerprint information for the query by comparing the fingerprint information in the classification database to the action performed by the user in relation to the query. The electronic marketplace may then modify a user experience for the user based at least in part on the fingerprint information. Additional details regarding evaluating a fingerprint for a query modifying a user's experience based on fingerprint information is discussed in detail in relation to FIG. 4.

FIG. 2 depicts an illustrative system or architecture 200 that depicts aspects of an electronic marketplace system, described herein. In architecture 200, one or more users 202 (i.e., electronic marketplace consumers or web browser users) may utilize user computing devices 204(1)-(N) (collectively, user devices 204) to access a browser application 206 (e.g., a web browser) or a user interface accessible through the browser application 206 via one or more networks 208.

In some aspects, the browser application 206 may be configured to receive, store, and/or display a website (e.g., an electronic marketplace website), or other interface on a display screen of the user devices 204. The browser application 206 may be hosted, managed, and/or provided by an electronic marketplace, such as by utilizing the service provider computers 210. In accordance with at least one embodiment, in addition to accessing the browser application 206 to view the electronic marketplace website, the users 202 may also utilize one or more native applications (e.g., a software application program) developed for use on a particular platform compatible with the user devices 204 to access the electronic marketplace website. The one or more service provider computers 210 may, in some examples, provide computing resources such as, but not limited to, data storage, data access, management, virtualization, cloud-based software solutions, electronic content performance management, and the like. The one or more service provider computers 210 may also be operable to provide web hosting, computer application development, and/or implementation platforms, combinations of the foregoing, or the like to the one or more users 202.

In some examples, the networks 208 may include any one or a combination of many different types of networks, such as cable networks, the Internet, wireless networks, cellular networks and other private and/or public networks. While the illustrated example represents the users 202 accessing the browser application 206 over the networks 208, the described techniques may equally apply in instances where the users 202 interact with the service provider computers 210 via the one or more user devices 204 over a landline phone, via a kiosk, or in any other manner.

The network 308 may be the same or similar as the networks 208 and 110 described above. The electronic device may include, for example, a cell phone 302, a laptop computer 304, or a tablet personal computer 306. User selections may be input by the user or other users, via one of the aforementioned various electronic devices via a web browser application (e.g., 206) on the user's device.

In accordance with at least one embodiment, the query fingerprint generation and classification service 230 may include a graphical user interface 314. The graphical user interface 314 may serve as the back-end component that may be configured to implement the various user interface elements that can be rendered on the user's browser application (e.g., 206) at the user devices. In accordance with at least one embodiment, the graphical user interface 314 may be configured to implement one or more user interface elements to enable users on devices 302, 304 and 306 to interact with the electronic marketplace website while searching for, browsing, or purchasing items via the electronic marketplace 110. As an example, a user may utilize a user interface element to submit a search query to the electronic marketplace. The user may utilize the user interface to view search results related to a query, various categories of information related to the query, and the like. The search query may be received by the communications manager 324 and stored in the user behavior database 114.

In accordance with at least one embodiment, the query fingerprint generation and classification service 230 may include a browsable electronic catalog 316 that is accessible over the network 308 to the users of user devices 302, 304 and 306, via the electronic marketplace website. The electronic catalog 316 may include a database of information about items that may be listed by users within the electronic marketplace system. The information may typically include item IDs, item descriptions and item images provided by manufacturers or distributors of the items. In some examples, information about the items listed in the electronic marketplace system may be viewable by the users of user devices 302, 304 and 306 by browsing the electronic catalog 316 wherein each item may fully be identified within a corresponding item detail page.

In some embodiments, the query fingerprint generation and classification service 230 may include a query fingerprint generation module 318. The query fingerprint generation module 318 may be configured to generate fingerprint information for one or more queries submitted by one or more users of the electronic marketplace. In one embodiment, the query fingerprint generation module 318 may be configured to access search query histories stored in the user behavior database 114 to identify a query submitted by one or more users of the electronic marketplace during a search session. The query fingerprint generation module 318 may perform one or more operations to identify a ‘first action’ performed by the users in relation to the query. As an example, the ‘first action’ may correspond to a ‘first query’ or an ‘initial query’ (e.g., ‘Shoes) submitted by the users. In some embodiments, the query fingerprint generation module 318 may perform one or more operations to store the ‘first action’ as fingerprint information associated with the query in the query classification database 116.

In accordance with some embodiments, the query fingerprint generation module 318 may then perform one or more operations to analyze a plurality of actions performed by the users in relation to the query, after the ‘first action’ and identify a ‘subsequent action’ based at least in part on the analysis. In one example, a ‘subsequent action’ may be identified as an action that is performed by a maximum number of users after the ‘first action.’ As an example, the query fingerprint generation module 118 may identify that a ‘subsequent action’ performed by a maximum number of users after submitting an initial query, ‘Shoes’ may be a re-formulation of the query to ‘Running Shoes.’ In certain embodiments, the query fingerprint generation module 318 may perform one or more operations to store the ‘subsequent action’ as fingerprint information associated with the query in the query classification database 116.

In some embodiments, the query fingerprint generation module 318 may then perform the operations discussed above to identify additional actions performed by the users after the ‘subsequent action’. The actions representing the fingerprint information thus identified may be used to generate a fingerprint for the query. In one embodiment, the fingerprint for the query may be represented as a vector of features, in which each feature in the vector represents an action performed by the users in relation to the query. In one embodiment, the last action in the fingerprint for the query may be identified as an ‘exit action’, indicating the end of the search session and/or an abandonment of the query by the users.

In some embodiments, the query fingerprint generation module 318 may also be configured to track the amount of time that each user spent browsing for information on a particular network page of the electronic marketplace website after submitting the query and before performing a ‘subsequent action’ that navigated the users to a second network page on the website. In embodiments, the query fingerprint generation module 318 may be configured to store the time information as fingerprint information associated with an action performed by the users in relation to the query.

Thus, in accordance with some embodiments, a fingerprint for a query may be represented by a schema ‘S,’ the schema comprising one or more attributes or features associated with the query such as time information and one or more actions performed in relation to the query during a search session. Accordingly, a fingerprint for a query may be represented by a schema ‘S’ as: (<average_amount_of_time_spent_on_page>, <action>), where <action> represents either a ‘first action’ or one or more ‘subsequent actions’ performed by the users in relation to the query and <average_amount_of_time_spent_on_page> represents an average amount of time spent by one or more users while browsing for information on a particular page of the website after performing the ‘first action’ and before performing a ‘subsequent action’ that navigated the users to the second page on the website. As an example, a fingerprint for a query may comprise fingerprint information such as <first query, 15 mins>, <re-formulation, 15 minutes>, <term addition, 10 minutes>, <exit, 0 minutes>.

In accordance with at least one embodiment, the query fingerprint information generation and classification service 230 may include a query fingerprint classification module 320. The query fingerprint classification module 320 may be configured to determine a classification for queries submitted by the users of the electronic marketplace based at least in part on the fingerprint information. In one embodiment, the classification of a query may be determined based at least in part on determining the duration of a search session related to the query, based on the time information in the fingerprint for the query. As an example, a relatively long search session may be indicative of multiple modifications of query terms by users during a search session whereas a relatively short search session may indicate fewer modifications to the query terms by users.

Accordingly, in one example, a query may be classified as a ‘Broad Query’ if the fingerprint information associated with the query indicates that the total number of actions in the fingerprint for the query and the total amount of time that the users stayed in the electronic marketplace website during the search session related to the query is within a first pre-determined threshold. In another example, a query may be classified as a ‘Well-defined Query’ if the fingerprint information associated with the query indicates that the total number of actions in the fingerprint for the query and the total amount of time that the users stayed on the electronic marketplace website during the search session related to the query is within a second pre-determined threshold. In other examples, a query may be classified as a ‘Brand Query’ if the fingerprint information associated with the query indicates brand-related information about the item (e.g., the name of a company which sells the item, product or service). In one embodiment, the pre-determined thresholds may be determined automatically by the electronic marketplace or may be specified by a user.

In other examples, a classification for a query may also be determined based at least in part on computing a similarity measure between the fingerprint information of the query and the fingerprint information of one or more other queries issued by the users of the electronic marketplace. As an example, the query fingerprint classification module 320 may be configured to compute the similarity measure between two queries by comparing the actions in the fingerprint information of the two queries and the order in which the actions appear in the fingerprint information. In accordance with at least one embodiment, the similarity measure may then be determined by assigning a value (e.g., such as ‘high’, medium’ or ‘low’) to each query based on the comparison. The query fingerprint classification module 320 may be configured to classify queries having a similarity measure of ‘low’ under a first category, classify queries having a similarity measure of ‘medium’ under a second category and classify queries having a similarity measure of ‘high’ under a third category, and so on.

In certain embodiments, the query fingerprint information generation and classification service 230 may be configured to determine a fingerprint for a query issued by a user based at least in part on combining the fingerprint information of one or more queries stored in the query classification database 116. As an example, consider that a user issues a query, ‘Men's Running Shoes Size 10.’ In one embodiment, the query fingerprint information generation and classification service 230 may determine that the fingerprint information for the query, ‘Men's Running Shoes Size 10’ exists in the query classification database 116 but is represented by a relatively small amount of data (e.g., the query was issued by a relatively small (1-2) number of users in the system and/or that the fingerprint information is representative of a relatively small (1-2) number of actions performed by the users). In this case, the query fingerprint information generation and classification service 230 may be configured to identify a similar query (e.g., ‘Men's Running Shoes’) stored in the query classification database 116 having a relatively large amount of data (e.g., the query was issued by a relatively large (>50) number of users in the system and/or that the fingerprint information is representative of a relatively large number (>5) number of actions performed by the users). In some embodiments, the query fingerprint information generation and classification service 230 may then be configured to determine a fingerprint for the query ‘Men's Running Shoes Size 10’ issued by the user by aggregating the fingerprint information of the query ‘Men's Running Shoes Size 10’ with the fingerprint information for the query, ‘Men's Running Shoes.’

In certain embodiments, the query fingerprint information generation and classification service 230 may include a dynamic network content generation module 322. In some embodiments, the dynamic network content generation module 322 may be configured to modify a user experience for the user based on a query issued by the user and based on fingerprint information related to the query. In one embodiment, the dynamic network content generation module 322 may be configured to perform one or more operations to receive a query issued by a user of a user device (e.g., 302, 304 or 306) and identify if fingerprint information exists for the query in the query classification database 116. If fingerprint information already exists for the query, the dynamic network content generation module 322 may determine a fingerprint for the query based on the fingerprint information in the database 116, and modify a user experience for the user based on the fingerprint. If fingerprint information does not exist for the query in the query classification database 116, then in some embodiments, the dynamic network content generation module 322 may perform one or more operations to access fingerprint information from the query classification database for a query that is similar to the user's query. As an example, a similar query may be defined as a query that may be classified under the same category as the query issued by the user in the electronic catalog. For example, a query (e.g., ‘Men's Shoes’) may be identified as a query that is similar to a query (‘Shoes’) submitted by the user, in certain embodiments. In one embodiment, the electronic marketplace may then perform one or more operations to determine a fingerprint for the query based on the fingerprint information and modify a user experience for the user based on the fingerprint.

In accordance with at least some embodiments, the dynamic network content generation module 322 may be configured to dynamically change the appearance of network content in a network page of the electronic marketplace website as the user searches for information about an item in the electronic marketplace website, based on the fingerprint information. Modifying the user experience in some embodiments may include rendering collected network site data (e.g., hypertext markup language, cascading style sheets, programming language instructions such as scripting language instructions) into network document images that may be displayed dynamically on the network page of the electronic marketplace website. In other embodiments, modifying the user experience may also include generating interactive network document regions that may change an appearance of the network page based on the fingerprint information of the query. For example, a ‘drop down’ menu may be dynamically generated to change the appearance of a network page in response to a user's query and the fingerprint information of the query. As another example, a region with refined search results may be dynamically displayed on the network page based on the fingerprint of the query. As an example, if the dynamic network content generation module 322 determines that users who search for an item ‘Games’ typically re-formulate their query to ‘Video games’ based on the fingerprint information, the dynamic network content generation module 322 may automatically modify the search results presented by the user to include ‘Video Games’ in a top region of the network document when the user submits a query for the item ‘Games.’

In certain embodiments, the dynamic network content generation module 322 may be configured to present a personalized search result for the user based on the fingerprint information. As an example, the dynamic network content generation module 322 may be configured to present a personalized search result to the user based on a query issued by the user and based on the fingerprint information related to the query. As an example, the dynamic network content generation module 322 may be configured to generate multiple views and/or layouts by which the user may view search results. For example, a personalized search result may include a search result that is presented in a particular layout and/or a view such as a ‘list view’, a ‘grid view’, an ‘image view’, and the like to the user. A personalized search result may include a search result that is presented in a particular layout and/or view to the user, based on the category of items in the search result, different products presented in the search result, and the like.

In some embodiments, the dynamic network content generation module 322 may be configured to present various categories of items related to the query issued by the user based on the fingerprint information and enable the user to navigate between the various categories of items within a given view and/or layout presented to the user in the search result. In embodiments, the generated views and/or layouts may identify a theme related to the query issued by the user and present various categories related to the theme in the search results.

In certain embodiments, the dynamic network content generation module 322 may be configured to present a subset of items related to a category of items in the search result, based on the fingerprint information of the query. As an example, the dynamic network content generation module 322 may organize search results based on category, order the categories based on fingerprint information and identify a subset of items related to a subset of categories (e.g., the most popular categories) to present to the user in the search result. Additional details of the manner in which the dynamic network content generation module 322 modifies a user experience for the user based on fingerprint information is discussed in FIG. 10 below.

FIGS. 4-6 illustrate example flow diagrams showing respective processes 400, 500 and 600 for generating and classifying query fingerprints for queries submitted by users of an electronic marketplace, described herein. These processes are illustrated as logical flow diagrams, each operation of which represents a sequence of operations that can be implemented in hardware, computer instructions, or a combination thereof. In the context of computer instructions, the operations represent computer-executable instructions stored on one or more computer-readable storage media that, when executed by one or more processors, perform the recited operations. Generally, computer-executable instructions include routines, programs, objects, components, data structures and the like that perform particular functions or implement particular data types. The order in which the operations are described is not intended to be construed as a limitation, and any number of the described operations can be combined in any order and/or in parallel to implement the processes.

Additionally, some, any, or all of the processes may be performed under the control of one or more computer systems configured with executable instructions and may be implemented as code (e.g., executable instructions, one or more computer programs, or one or more applications) executing collectively on one or more processors, by hardware, or combinations thereof. As noted above, the code may be stored on a computer-readable storage medium, for example, in the form of a computer program including a plurality of instructions executable by one or more processors. The computer-readable storage medium may be non-transitory.

In some examples, the query fingerprint generation and classification service 230 (e.g., utilizing at least the query fingerprint generation module 318, the query fingerprint classification module 320 and the dynamic network content generation module 322) shown in at least FIG. 3 (and others) may perform the processes 400, 500 and 600 of FIG. 4, FIG. 5 and FIG. 6 respectively.

FIG. 4 illustrates a flow diagram of an example process 400 for generating a query fingerprint for one or more queries submitted by users of an electronic marketplace, described herein. The process at 400 may begin at 402 by identifying a query submitted by one or more users during a search session. In one example, a query submitted by the users may be identified by accessing user search query histories stored in the user behavior database (e.g., 114). At 404, the process 400 may include identifying a ‘first action’ performed by the users in relation to the query. As discussed above, a ‘first action’ may correspond to a ‘first query’ or an ‘initial query’ (e.g., ‘Shoes) submitted by the users. At 406, the process 400 may include storing the ‘first action’ as fingerprint information associated with the query in the query classification database 116. In some embodiments, the process at 406 may also include storing time information related to the identified action. As discussed above, the time information may correspond to an average amount of time that one or more users spent browsing for information on a particular page of the website after performing the ‘first action’ and before performing a ‘subsequent action’ that navigated the users to a second page on the website.

In some embodiments, at 408, the process 400 may include analyzing a plurality of actions performed by the users in relation to the query, after the identified action (e.g., ‘first action’). At 410, the process 400 may include identifying a ‘subsequent action’ based at least in part on the analysis. At 412, the process 400 may include storing the ‘subsequent action’ and the time information associated with the ‘subsequent action’ as fingerprint information associated with the query in the query classification database 116.

At 414, the process 400 may include identifying if the ‘subsequent action’ corresponds to an ‘exit action’ performed by the users in relation to the query. In one embodiment, an ‘exit action’ may correspond to an abandonment of the query by the users or the end of the search session by the users. If the ‘subsequent action’ is indicative of an ‘exit action’, then in one embodiment, the process 400 ends at 416, by generating a fingerprint for the query that includes the identified actions. In one embodiment, and as discussed above, the fingerprint information for the query may be represented as a vector of features, in which each feature or attribute corresponds to an action performed by the user in relation to the query and may include time information associated with each action.

At 414, if it is determined that the subsequent action does not correspond to an ‘exit’ action, then the process 400 continues to 408 to analyze a plurality of actions performed by the users in relation to the query after the identified action.

FIG. 5 illustrates a flow diagram of an example process 500 for evaluating fingerprint information for a query submitted by a user and classifying the query based on the fingerprint information, described herein. The process at 500 may begin at 502 by receiving a query issued by a user of the electronic marketplace. At 504, the process 500 may include accessing a query classification database (e.g., 116) having fingerprint information. In some embodiments, at 506, the process 500 may include determining a fingerprint for the query by comparing the fingerprint information in the query classification database to an action performed by the user in relation to the query. As an example, an action may correspond to an ‘initial query’ (e.g., ‘Shoes’) submitted by the user. In one example, the process at 506 may include comparing search terms corresponding to a plurality of queries stored in the query classification database to the search term (e.g., ‘Shoes’) of the initial query issued by the user. If a search term of a query stored in the query classification database corresponds to the search term of the query issued by the user, then in some embodiments, the process at 506 may include obtaining the fingerprint information of the query stored in the query classification database to determine a fingerprint for the query issued by the user. If the search term of the query issued by the user does not correspond to one or more search terms of queries stored in the query classification database, then in some embodiments, the process at 506 may include obtaining the fingerprint information of a query in the query classification database that is similar to the query issued by the user. A similar query may be determined in various ways. As an example, a similar query may be defined as a query that may be classified under the same category as the query issued by the user in the electronic catalog. For example, a query (e.g., ‘Footwear’) may be identified as a query that is similar to a query (‘Shoes’) submitted by the user, in certain embodiments. In one embodiment, the process at 506 may then include determining a fingerprint for the query based on the fingerprint information. At 508, the process 500 may include determining a classification for the query based on the fingerprint.

FIG. 6 illustrates a flow diagram of an example process 600 for modifying a user experience for a user for a query submitted by the user based on fingerprint information, described herein. The process at 600 may begin at 602 by receiving a query submitted by a user of the electronic marketplace. At 604, the process 600 may include identifying a ‘first action’ associated with the query. As an example, the ‘first action’ may correspond to the ‘first query’ or the ‘initial query’ (e.g., ‘Shoes) submitted by the user. At 606, the process 600 may include accessing the query classification database (e.g., 116) having fingerprint information. At 608, the process 600 may include identifying if fingerprint information is available for the query in the query classification database 116.

If fingerprint information already exists for the query, at 610, the process 600 may include determining a fingerprint for the query based on the fingerprint information. If fingerprint information does not exist for the query in the query classification database (e.g., 116), then in some embodiments, the process 600 may include accessing fingerprint information from the classification database (e.g., 116) to identify a query that is classified under a same category as the query issued by the user. As an example, if the user submitted a query (‘Shoes’) and it is determined that fingerprint information does not exist for the query (‘Shoes’) in the classification database, then, in some embodiments, the process 600 may access fingerprint information for a query (‘Footwear’) that is classified under the same category as the query (‘Shoes’) issued by the user.

At 612, the process 600 may include determining a classification for the query based on the fingerprint. As an example, the process 600 may determine that a query (‘Shoes) issued by the user is a ‘Broad query’ based on the fingerprint information. In one embodiment, at 614, the process 600 may include modifying a user experience for the user based on the fingerprint information and classification. In some embodiments, modifying the user experience may also include identifying a ‘subsequent action’ based on the fingerprint for the query and dynamically changing the appearance of network content in a network page of the electronic marketplace website based on the ‘subsequent action’ and the classification of the query. As an example, the process at 614 may identify that a ‘subsequent action’ for a query, ‘Shoes’ submitted by a user is a re-formulation of the query based on the fingerprint. In one embodiment, the process at 614 may then perform an operation to dynamically change the appearance of network content in a network page of the electronic marketplace website to display search results related to ‘Running Shoes’ to the user. Additional details of the manner in which a user experience for a user may be modified based on fingerprint information is discussed in relation to FIGS. 7-9, described herein.

FIG. 7 is a schematic diagram depicting an example graphical user interface by which a user can search for an item within an electronic marketplace, described herein. In FIG. 7, the example environment 700 may be a graphical user interface viewable via a browser application (e.g., via the browser application 206) on the user's device. In the example illustrated in FIG. 7, the user submits a search query “Games’ via the search query interface 702 provided by the electronic marketplace website. The electronic marketplace may then identify a subsequent action that the user is likely to perform in relation to the query ‘Games’ based on the fingerprint information stored in the query classification database. As an example, the electronic marketplace may determine that users who search for the item ‘Games’ typically re-formulate their query to ‘Video games’ based on the fingerprint information. In some examples, the electronic marketplace may also determine that the query ‘Games’ is classified as a ‘Broad Query’ in the query classification database based on the fingerprint information. In one embodiment, the electronic marketplace may dynamically modify the search results presented to the user to include various categories of ‘Video games.’ In the example illustrated in FIG. 7, the electronic marketplace modifies the search results presented by the user by dynamically generating and displaying a region 704 with refined search results of various categories of ‘Video games’ on a network page 706 to the user, based on the fingerprint information and the classification of the query.

FIG. 8 is a schematic diagram depicting an example graphical user interface by which a user can search for an item within an electronic marketplace, described herein. In FIG. 8, the example environment 800 may be a graphical user interface viewable via a browser application (e.g., via the browser application 206) on the user's device. In the example illustrated in FIG. 8, the user submits a search query “Games’ via the search query interface 802 provided by the electronic marketplace website. The electronic marketplace may then identify a subsequent action that the user is likely to perform in relation to the query ‘Games’ based on the fingerprint information and the classification of the query ‘Games’ from the query classification database. The electronic marketplace may then dynamically modify the search results presented to the user to include ‘Video games.’ In the example illustrated in FIG. 8, the electronic marketplace may modify the search results presented to the user by dynamically generating and displaying a ‘drop down’ menu 804 that changes the appearance of the network page 806 in response to the user's query and the fingerprint information of the query to display different categories of ‘Video games’ to the user.

FIG. 9 is a schematic diagram depicting an example graphical user interface by which a user can search for an item within an electronic marketplace, described herein. In FIG. 9, the example environment 900 may be a graphical user interface viewable via a browser application (e.g., via the browser application 206) on the user's device. In the example illustrated in FIG. 9, the user submits a search query ‘Bikes’ via the search query interface 902 provided by the electronic marketplace website. The electronic marketplace may identify a subsequent action that the user is likely to perform in relation to the query ‘Bikes’ by accessing the fingerprint information and the classification of the query ‘Bikes’ stored in the query classification database. The electronic marketplace may then dynamically modify the search results presented by the user to include various types of ‘Outdoor Bikes’ as the user queries for the item ‘Bikes’ via the search interface. In the example illustrated in FIG. 9, the electronic marketplace may modify the search results presented by the user by dynamically generating and displaying a region 904 with refined search results of various categories of ‘Outdoor Bikes’ on the network page 906 to the user, based on the fingerprint information.

Illustrative methods and systems for the generation and classification of query fingerprints are described above. Some or all of these systems and methods may, but need not, be implemented at least partially by architectures such as those shown at least in FIGS. 1-9 above. The discussion below relates to methods and systems for modifying search results presented to a user based on query fingerprint information. Some or all of these systems and methods may, but need not, be implemented at least partially by architectures such as those shown at least in FIGS. 10-36 below.

FIG. 10 illustrates an example architecture 1000 of the dynamic network content generation module 322 provided by the query fingerprint generation and classification service discussed in FIG. 3, in accordance with at least one embodiment of the present disclosure. The dynamic network content generation module 322 may include a plurality of modules configured to implement functionality of the dynamic network content generation module 322, described herein. The modules 1002 may be software modules, hardware modules, or a combination thereof. The modules may be configured in the manner suggested in FIG. 1000 or may exist as separate modules or services external to the dynamic network content generation module 322.

In accordance with at least one embodiment, the dynamic network content generation module 322 may include a layout generation module 1004, an interactive network region generation module 1006, a category identification module 1008 and a rendering engine 1010. In some embodiments, and as will be discussed in detail below, the layout generation module 1004, the interactive network region generation module 1006 and the category identification module 1008 may be configured to dynamically modify search results presented to a user based on fingerprint information related to a query. In accordance with at least one embodiment, the rendering engine 1010 may be configured to provide information for rendering a network page comprising the modified search results to the user.

Modifying the search results, in some examples, may include arranging items in the search results presented to the user, in accordance with one or more layouts and/or views based on query fingerprint information. Modifying search results may include generating an interactive network region comprising the search results related to a query issued by a user, based on fingerprint information. In some examples, modifying search results may include identifying various categories of items related to a query issued by the user based on fingerprint information, organizing the search results based on categories, ordering the categories based on fingerprint information and identifying a subset of items related to a subset of categories (e.g., the most popular categories) in the search results.

In accordance with at least one embodiment, the layout generation module 1004 may be configured to dynamically modify search results presented to a user by arranging the items in the search results in at least one of a ‘list’ layout, a ‘grid’ layout or an ‘image’ layout, based on query fingerprint information. In some embodiments, when a user submits a query via a search interface provided by the electronic marketplace, the fingerprint generation module (e.g., 318 shown in FIG. 3) may identify a subsequent action performed by a plurality of users of the electronic marketplace in relation to the query based on fingerprint information stored in the query classification database. The layout generation module 1004 may then dynamically modify search results presented to the user based on the fingerprint information. In one example, the layout generation module 1004 may modify search results presented to the user by arranging items of the search result in a two-dimensional, scrollable ‘grid’ layout, based on the fingerprint information. In other examples, the layout generation module 1004 may modify search results presented to the user by arranging the items of the search result in a vertical list of scrollable items, based on the fingerprint information. In other embodiments, the layout generation module 1004 may modify search results presented to the user by arranging ‘images’ of the items of the search result, based on the fingerprint information. In embodiments, the rendering engine 1010 may be configured to provide information for rendering a network page comprising items of the search results arranged in accordance with a layout as discussed above, based on the fingerprint information. The manner in which the layout generation module 1004 may dynamically modify search results presented to a user is discussed in relation to FIGS. 11-13.

FIG. 11 is an exemplary illustration of modified search results presented to a user in which items of the search results are arranged in accordance with a ‘list’ layout, based on fingerprint information related to a query. In FIG. 11, the example environment 1100 may be a graphical user interface viewable via a browser application (e.g., via the browser application 206) on the user's device. In the example illustrated in FIG. 11, a user submits a search query ‘phone case’ via a search query interface 1102 provided by the electronic marketplace website. The query fingerprint generation module (e.g., 318) may identify a subsequent action that the user is likely to perform in relation to the query ‘phone case’ based on fingerprint information stored in the query classification database. As an example, the query fingerprint generation module (e.g., 318) may identify that the subsequent action may be a ‘term addition’ to the query that describes, for example, additional characteristics of the query such as the color of the phone case, the size of the phone case, a particular brand of the phone, and so on. The layout generation module 1004 may then be configured to dynamically modify the search results presented to the user to include items related to these additional characteristics. In the illustrated example shown in FIG. 11, the layout generation module 1004 may modify the search results presented to the user by arranging the items of the search result in a list of scrollable items 1104, based on the fingerprint information.

FIG. 12 is an exemplary illustration of modified search results presented to a user in which items of the search results are arranged in accordance with a ‘grid’ layout, based on fingerprint information related to a query. In FIG. 12, the example environment 1200 may be a graphical user interface viewable via a browser application (e.g., via the browser application 206) on the user's device.

FIG. 34 illustrates aspects of an example environment 3400 for implementing aspects in accordance with various embodiments. As will be appreciated, although a Web-based environment is used for purposes of explanation, different environments may be used, as appropriate, to implement various embodiments. The environment includes an electronic client device 3402, which can include any appropriate device operable to send and receive requests, messages or information over an appropriate network 3404 and convey information back to a user of the device. Examples of such client devices include personal computers, cell phones, handheld messaging devices, laptop computers, set-top boxes, personal data assistants, electronic book readers and the like. The network can include any appropriate network, including an intranet, the Internet, a cellular network, a local area network or any other such network or combination thereof. Components used for such a system can depend at least in part upon the type of network and/or environment selected. Protocols and components for communicating via such a network are well known and will not be discussed herein in detail. Communication over the network can be enabled by wired or wireless connections and combinations thereof. In this example, the network includes the Internet, as the environment includes a Web server 3406 for receiving requests and serving content in response thereto, although for other networks an alternative device serving a similar purpose could be used as would be apparent to one of ordinary skill in the art.

The illustrative environment includes at least one application server 3408 and a data store 3410. It should be understood that there can be several application servers, layers, or other elements, processes or components, which may be chained or otherwise configured, which can interact to perform tasks such as obtaining data from an appropriate data store. As used herein the term “data store” refers to any device or combination of devices capable of storing, accessing and retrieving data, which may include any combination and number of data servers, databases, data storage devices and data storage media, in any standard, distributed or clustered environment. The application server can include any appropriate hardware and software for integrating with the data store as needed to execute aspects of one or more applications for the client device, handling a majority of the data access and business logic for an application. The application server provides access control services in cooperation with the data store and is able to generate content such as text, graphics, audio and/or video to be transferred to the user, which may be served to the user by the Web server in the form of HyperText Markup Language (“HTML”), Extensible Markup Language (“XML”) or another appropriate structured language in this example. The handling of all requests and responses, as well as the delivery of content between the client device 3402 and the application server 3408, can be handled by the Web server. It should be understood that the Web and application servers are not required and are merely example components, as structured code discussed herein can be executed on any appropriate device or host machine as discussed elsewhere herein.

The data store 3410 can include several separate data tables, databases or other data storage mechanisms and media for storing data relating to a particular aspect. For example, the data store illustrated includes mechanisms for storing production data 3412 and user information 3416, which can be used to serve content for the production side. The data store also is shown to include a mechanism for storing log data 3414, which can be used for reporting, analysis or other such purposes. It should be understood that there can be many other aspects that may need to be stored in the data store, such as for page image information and to access right information, which can be stored in any of the above listed mechanisms as appropriate or in additional mechanisms in the data store 3410. The data store 3410 is operable, through logic associated therewith, to receive instructions from the application server 3408 and obtain, update or otherwise process data in response thereto. In one example, a user might submit a search request for a certain type of item. In this case, the data store might access the user information to verify the identity of the user and can access the catalog detail information to obtain information about items of that type. The information then can be returned to the user, such as in a results listing on a Web page that the user is able to view via a browser on the user device 3402. Information for a particular item of interest can be viewed in a dedicated page or window of the browser.

Each server typically will include an operating system that provides executable program instructions for the general administration and operation of that server and typically will include a computer-readable storage medium (e.g., a hard disk, random access memory, read only memory, etc.) storing instructions that, when executed by a processor of the server, allow the server to perform its intended functions. Suitable implementations for the operating system and general functionality of the servers are known or commercially available and are readily implemented by persons having ordinary skill in the art, particularly in light of the disclosure herein.

The environment in one embodiment is a distributed computing environment utilizing several computer systems and components that are interconnected via communication links, using one or more computer networks or direct connections.
